Electrical connection and oil bath therefor



Feb. 3, 1931. w. T. RUNKLE ELECTRICAL CONNECTION AND OIL BATH THEREFOR Filed Jan. 7, 1950 Inventor William T Run/We w A ttomey Patented Feb. 3, 1931 WILLIAM T. EUNKLE, 03 ED IPASO, TEXAS, ASSIG-NOR OF FORTY-FIVE ONE-HUN- DREDTHS T0 GUS GERDIN, OF EL PASO, TEXAS ELECTRICAL CONNECTION AND OIL BATH THEREFOR Application filed January 7, 1930.

The present invention relates broadly to electrical connections, and has more particular reference to an electrical connection for all. electric batteries, transformers or other devices where an electrical connection is used and has more particular reference to such a connection having a cup for oil or any other fluid associated therewit whereby the connection may be continuallv maintained in a bath of oil or any other l thus preventin corroding of the clectri al connection.

The primary object of this invention is therefore to provide an especially to; oil cup for use with the electrical connection for maintaining the connection bathed in oil or any other fluid.

A still further object of the invention is LO provide a connection of this character which is simple, will involve or require but a minimum amount of time in making the co c tion and which will be thoroughly reliable and practical for retaining the connection in a bath of oil or any other fluid.

@ther objects and advantages of the invention will become apparent during; a study of the following description, taken in connection with the accompanying drawings, wherein taken through the cup and showing the same applied to an electrical connection,

Figure 2 is a horizontal sectional view taken. substantially on the line 22 of Figure 1.

With reference more in detail to the drawings it will be seen that l have denoted the electrical socket or pole which may be in th nature of. a battery terminal or the like indicated generally by the reference character 5.

As comprehended by the present invention, the pole 5 is threaded as at 6 and at its upper end is provided with a somewhat conical or inwardly tapering recess. or socket 7 adapt ed to receive the similarly shaped connector plug 8, which plug 8 has secured thereto in any suitable manner one o .d of the electrical connector cord or cable 9 as shown to advantage in Figure 1.

The cable plug 8 has fitting conformably thereon sleeve or cap 10, said plug and cap being of course made of copper.

Serial No. 419,070.

To retain the plug within the socket of the post 5 there is provided a retaining nut 11 threadedly engaged with the post 5, and said nut has formed integrally therewith a cylindrical cap like portion or member 12 which is internally threaded as at 13 forthrcaded engagement with said post.

The nut cap 12 has a central opening 14 to accommodate the reduced portion 15 of said plug. (See Figure 1.).

in rder to maintain the electrical connection above described, in a bath of oil or any other fluich there is provided a cup designated generally by the reference character G. The cup C is preferably made of rubber or other suitable durahlc or strong material or composition, and comprises the lower or container section 16 and the upper or cap section 17.

As shown to advantage in Figure 1 the lower or container section of the cup 16 has a central intenally threaded opening 18 for threaded engagement with the post 5, and said cup section 16 is threaded on the post at the bottom of the post.

Said cup section 16 is provided with an annular internally threaded flange 19 for threaded engagement with the complementary threaded lower reduced portion 20 of the cap forming cup section 17, said reduced portion 20 of the cap section forming an external annular shoulder 21 which rests upon the upper edge of the flange 19 and, acts somewhat as a stop for the cup section 16 when said sections 16 and 1'? are thrcedcdly connected together as in Figure 1.

The cap Iormiug section 17 oithe cup is of cylindrical formation and at its upper closed end has a centrally located opening 22 through which extends the conductor cord or cable 9, said conductor cord or cable 9 fitting snugly within the opening 2.

Manifcstly, in using the cup. oil or any other fluid may firs be deposited within the cup section 16 the cup section 16 having been previously threaded on the post 5 placing the retaining nut 11 in engagement with the postaftcr which that is the placing of the oil cup section 16 in place, the cap section 1'? may be then threadedly engaged with the cup section 16 it being understood of prior to course that at such time, the plug 18 and nut 11 have been placed in proper connecting po sition. As an alternative the cap section 17 of the cup provided With a suitable feeding opening not shown through which oil or any other fluid may be passed into the cup after the connection and cup C have all been placed in their proper position in completing the electrical connection.

It is thought that from the foregoing description, taken in connection with the accompanying drawings, a clear understand ing of the operation, utility and advantages of a connection of this character will be had by those skilled in the art without a more detailed description thereof.

Having thus described my invention, What I claim as new is:

1. In a non-corroding terminal connection of the character described, an electrical connector post having a socket, an electrical conductor provided at one end with a current conducting plug receivable in said socket, a cap nut engaging said plug and said post for retaining said plug in said socket. and a fluid containing cup completely enclosing said nut, said cup comprising a pair of sections, means for detachably connecting said sections, one of said sections having an opening to accommodate the electrical concuctor cable, and the other of said sections having a centrally arranged opening to accommodate said electrical post.

2. In a non-corroding terminal connection of the character described, an electrical connector post having a socket, an electrical conductor provided at one end with a current conducting plug receivable in said socket, a cap nut engaging said plug and said post for retaining said plug in said socket, and a fluid containing cup completely enclosing said nut, said cup including a bottom comprising a fluid containing section to accommodate said post, and an internally threaded flange, and a cap forming section having a reduced externally threaded portion for threaded engagmieut with said internally threaded flange, said cap section having a central opening to accon'nnodate the electrical cable.

In a non-corroding terminal connection of the character described, an electrical connector post having a socket, an electrical conductor provided at one end with a current conducting plug receivable in said socket, a cap nut engagiin said plug and said post for retaining said plug in said socket, and fluid containing cup completely enclosing said nut, said cup including a bottom comprising a fluid containing section to accommodate said post, and an internally threaded flange, and a cap forming section having a reduced externally threaded portion for threaded engagement with said internally threaded flange, said cap section having a central opening to accommodate the electrical WILLIAM T.
